Produced in 1976 by Hanna-Barbera for Georgetown University's Center for Strategic and International Studies and narrated by Charlton Heston, Energy: A National Issue was an earnest animated public-service film distributed to schools on 16 mm and syndicated to television in 1977. Styled as a brisk historical tour of energy use, it brought Fred and Wilma Flintstone through prehistoric fires, Roman baths, colonial hearths and suburban 1970s kitchens to teach efficiency — a deceptively light educational piece with high-profile backing and an unusually wide non-theatrical release strategy for Hanna-Barbera work of the period.
Lending a sombre footnote to an otherwise didactic special, the film is notable for being the final Flintstones production to feature Alan Reed as the voice of Fred Flintstone; his parts were recorded very shortly before his death in 1977. The juxtaposition — a jaunty, family-friendly energy PSA carrying the last recorded performance of a beloved Golden Age television character — turned the project into an unintended valedictory moment. For audiences in classrooms around the country it became one of the last places to hear Reed’s archetypal gravelly Fred, making the modest educational short an unexpected memorial within the wider, decades-long Flintstones legacy.
